The included ferrule and crimp contact are sized for that cable group, so the shield termination (crimp) and centre conductor termination (crimp) are a matched set. Using a different cable type will change the impedance match and the mechanical grip — stick with the listed cable or verify the crimp dimensions against your cable's OD and dielectric diameter. ## 500 Mating Cycles with Bayonet Lock The bulkhead mount with front-side nut and included gasket provides a weather-resistant panel seal when torqued correctly.","metaTitle":"Amphenol RF 031-70566-12G BNC Jack, 75 Ohm, 12 GHz","metaDescription":"Amphenol RF 031-70566-12G BNC jack, 75 Ohm impedance, 12 GHz max frequency, panel mount bulkhead kit.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Features":"-","Includes":"6 pcs - 1 Connector, 1 Contact, 1 Ferrule, 1 Gasket, 1 Lockwasher, 1 Nut","Impedance":"75 Ohms","Packaging":"Bulk","Body Finish":"Nickel","Cable Group":"Belden 4855R","Part Status":"Active","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"-","Connector Style":"BNC","Frequency - Max":"12 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"031-70","Contact Termination":"Crimp","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C ~ 165°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.2400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/962ffe0c2c33b3176c2bd28cfde9764c.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-70566-12G/alternatives.json"},"ai":{"faq":[{"question":"What cable does 031-70566-12G work with?","answer":"It is designed for Belden 4855R cable.
